The reason that 999000 is the master
I'm just going to throw my experience out there:
999000 isn't very good. I've probably encountered him 30-40 times and almost always kill his entire formation. In all of those encounters, I've lost two (2) planes to him, out of 60-100 kills on him. He's always been a nice, fun guy; but, I don't see anything difficult about downing him.
I find SHawk to be a vastly better bomber pilot, and honestly much more deadly than 999000.
While Wizz isn't as lethal as SHawk, I also find him harder to kill. That is to say, while SHawk might shoot me down more than the average bomber pilot, Wizz is less likely to die.
